Error adding integer auto-increment column with migration (since 8.0.1)

[atsidaev]

Steps to reproduce

Here is the minimal reproducible example. Use an empty database and the following data context:

using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using Microsoft.EntityFrameworkCore;
public class ApplicationDbContext : DbContext
{
	public DbSet<User> Users { get; set; }
	protected override void OnConfiguring(DbContextOptionsBuilder modelBuilder)
	{
		var connectionString = "..."; 
		modelBuilder.UseMySql(
			connectionString,
			ServerVersion.AutoDetect(connectionString));
	}
}
public class User
{
	[Key]
	[Required, MaxLength(32)]
	public string Name { get; set; }
}

Create initial migration

dotnet ef migrations add Migration1

Change User class this way (i.e. remove an old key and add new auto-incremented integer key field)

public class User
{
	[Required, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
	public int Id { get; set; }
	[Required, MaxLength(32)]
	public string Name { get; set; }
}

Add migration:

dotnet ef migrations add Migration2

Now attempt to create the table in the database:

dotnet ef database update

An error is occurred. This happens starting from 8.0.1 version of Pomelo.EntityFrameworkCore.MySql. 8.0.0 works as expected.

The issue

This is the log with the exception:

I compared dotnet ef migrations script result for versions 8.0.0 and 8.0.2 of Pomelo.EntityFrameworkCore.MySql, and I see that for 8.0.0 there was two-step procedure. AUTO_INCREMENT was not set directly in the ALTER TABLE call, instead of this the POMELO_AFTER_ADD_PRIMARY_KEY procedure was used with some auto-detection logic for identity columns inside.

ALTER TABLE `Users` ADD `Id` int NOT NULL DEFAULT 0;

ALTER TABLE `Users` ADD CONSTRAINT `PK_Users` PRIMARY KEY (`Id`);
CALL POMELO_AFTER_ADD_PRIMARY_KEY(NULL, 'Users', 'Id');

And for 8.0.2, despite the POMELO_AFTER_ADD_PRIMARY_KEY procedure still exists in the migration script, it is not called. The column is created directly with DEFAULT 0 AUTO_INCREMENT combination of params, which cannot be accepted by MySQL Server for some reason.

ALTER TABLE `Users` ADD `Id` int NOT NULL DEFAULT 0 AUTO_INCREMENT,
ADD CONSTRAINT `PK_Users` PRIMARY KEY (`Id`);
